Abstract

The intricate network of the pancreatic nervous system plays a fundamental role in physiologic functions of the endocrine and exocrine pancreas. Several pancreatic diseases affect the normal functionality of the pancreatic nervous system. This chronic derangement leads to anatomical alterations, such as neural hypertrophy and increased nerve density. Perineural invasion is a prominent feature of pancreatic cancer, contributing to cancer progression and metastasis. Despite the fact that these pathogenic mechanisms are still incompletely studied and understood, the constant occurrence of these alterations highlights their importance in the pathophysiology of the pancreatic diseases. The occurrence of anatomical changes is strictly linked to the appearance of pain. Pancreatic pain has peculiar features, and its management is complex in clinical practice. In the present review, the evidence on lifestyle, pharmacological and interventional approaches for the management of pancreatic pain is presented. Analgesic therapy is the cornerstone of pain treatment. However, it is important to identify the individual characteristic of the patients and personalize the approach to pain management. Nevertheless, the incomplete efficacy of these strategies makes this field an area of unmet needs. The study of neuroplasticity is crucial to understand the mechanisms that regulate the pathophysiology of pancreatic diseases. Several trials testing new drugs with specific neuromodulatory effects are ongoing. However, further studies are needed to investigate crucial targets to develop novel therapies for the modulation of the nervous system and the prevention of complications of pancreatic diseases. This comprehensive review summarizes the importance of the nervous system in pancreatic diseases with a special focus on its anatomy and physiology, its pathophysiological features and clinical relevance in pancreatic disease, the treatment of pancreatic pain, and the identification of future trends of research.

Pretraining has recently greatly promoted the development of natural language processing (NLP)
We show that M6 outperforms the baselines in multimodal downstream tasks, and the large M6 with 10 parameters can reach a better performance
We propose a method called M6 that is able to process information of multiple modalities and perform both single-modal and cross-modal understanding and generation
The model is scaled to large model with 10 billion parameters with sophisticated deployment, and the 10 -parameter M6-large is the largest pretrained model in Chinese
Experimental results show that our proposed M6 outperforms the baseline in a number of downstream tasks concerning both single modality and multiple modalities We will continue the pretraining of extremely large models by increasing data to explore the limit of its performance
